T all whom it may concern: Y 1

Bc it known that I, FREDERICK S; BARUS, of Jersey City,lin the county of Hudson and State of New Jersey, have invented a new and Improved Machine for Forming Paper Tubes, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved machine for forming paper tubes used in the manufacture of fireworks and for other purposes, the machine being very simple and durable in construction and arranged to produce a large number of tubes at each operation.

The invention consists principally of a rolling-table, a recessed head on the said table,

and a slidable mandrel-frame carrying a revoluble mandrel adapted to engage the paper in the said recessed head.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of the improvement. Fig. 2 is a plan view of the same. Fig. 3 is aV transverse section of the same on the line 3 8 of Fig. 2. Fig. 4 is a plan view of the improvement with the parts ina different position. Figp is asectional side elevation of the rolling-table, the paper-lifting bar, and the recessed head. Fig. 6 is a similar view with the lifting-bar withdrawn and the paper resting on the head. Fig. 7 is a like view of the same with the mandrel-frame advanced and the mandrel engaging the paper in the recessed head. Fig.8 is a like View of the rolling-table, the mandrel, and

' the recessed head in a different position; and

Fig. 9 is a sectional side elevation of the rolling-table and the mandrel, showing the wind-` ing up of the paper on themandrel.

The improved machine for forming paper tubes is mounted on a suitably-constructed frame A, supporting at its forward end a slightlyinclined rollin g-table B, on which the sheet of paper() is placed, the forward edge of the paper abutting against a gage `D, pivv oted at'D on the sides of the rolling-table B to permit of swinging the said gage ont of the way when cutting the paper C into strips by spaced cutting disks or knives E on a shaft journaled in a frame F, provided with a rod F', journaled in the sides of a mandrel-frame G, carrying a mandrel II. The revoluble knives E are spaced such a distance apart as to correspond to the length of the tubes to be formed,jthecutting edges of the knives be ing adapted to pass into longitudinally-extending recesses or grooves B', formedl on the top of the rolling-table B, as is plainly shown in the drawings.

Now when the paper is placed in position on the rolling-table B and engaged thereon with the gage D then thelatter is swung over to the position shown in Fig. l, and then the frame Gis slid forward to cause the knives or disks E to cut the paper C into small strips, each for forming a tube. jWhen this has'been done, the frame G is moved back to its former position, so as to leave the single strips of paper free on the rolling-table. The frame F, carrying the knivesE, is now swung upward and rearward into the position shown in Figs, 4 and 7 to leave the table free for the rolling of the strips into tubes. A transversely-extending bar I, normally resting in a recess in the rollingtable B, is now pushed upward to lift the forward ends of the strips of paper, as plainly illustrated in Fig. 5, for theinsertion of a recessed head J, secured to arms J', attached to a Atransverse bar J2, adapted to rest on blocks K, secured to the topof the rollingtable B,'at or near the vupper end thereof.'

` The transverse bar I is secured to the upper ends of arms I', attached to a transversely-extending Ashaftlz, journaled in suitable bearings inuthe sides of the frame A, and` on the said shaft is fastened a lever 13, adapted to be taken hold of bythe operator to impart a rocking motion` to the shaft I2, so as tomove the bar I upward to lift the forward ends of the strips of paper, as above mentioned, and shown in Fig. 5. Vhen this takes place, the

head J can be readily inserted under the liftedup ends of the strips 0f paper, and after this has been done the operatorreleases the lever I3 to permit the springs I4, pressing on the arms I', toreturn the bar I to its'former position, as

IOO

shown in Fig. 6, thus leaving the free ends of the strips of paper resting on the head J as shown in Fig. 6. The operator now slides the frame G again forward, so that the mandrel II passes over the strips of paper and upon the raised end of the strips to press the same into the concave recess of the said head, as plainly indicated in Fig. 7. Vhen this has been done, the operator takes hold of the transverse bar J 2 to swing the head J over, said head being in engagement with the ends of the strips of paper, so that the head finally assumes the position shown in Fig. S, thus causing the extreme ends of the paper to be wound around the mandrel to insure a proper rolling up of the strips when turning the mandrel. The mandrel is now turned, and for this purpose is provided at one end with a wheel II', having a handle H2, under the control of the operator. As soon as one turn is made the operator can -remove the head J from the machine and keep on turning the mandrel to completely wind up the strips of paper on the mandrel. The strips of paper are provided on their top surfaces with a suitable gum or other adhesive substance for properly attaching the several layers to each other. When the strips have been wound upon the mandrel, then the frame G is moved back to its former position, as shown in Fig. l, and then the operator pulls on the wheel H, so as to withdraw the other end of the mandrel H from its bearing and to cause the Several tubes formed on the mandrel to be pushed therefrom to drop down between the sides of the frame A into a suitable receptacle provided for the purpose.

In order to insure a proper withdrawing ofy the mandrel for removing the tubes, I provide a lateral guideway L for the wheel H, so as to prevent wabbling of the mandrel while pushing the tubes off the same. It is understood that the tube next to the bearing adjacent to the wheel H abuts against the bearing upon withdrawing the mandrel, so as to cause a pushing off of the rest of the tubes, and when the mandrel is finally withdrawn past the last tube the latter drops down into the receivi11g-receptacle.

In order to insure a proper cutting of the paper by the knives or cutters Il, I provide the frame F with fingers F2, extending between tlie cutters and adapted to pass on top of the paper C when the frame G is iirst moved upon the rolling-table B, so that the knives cut properly without danger of lifting up the strips of paper when returning the frame to its former position.

It will be seen that by the arrangement described thc sheet of paper is Iirst eut into strips, and the strips are then wound up on the mandrel for forming a large number of tubes at one time.

The machine is very simple and durable in construction and is not liable to get out of order.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A machine for forming paper tubes, comprising a rolling-table, a recessed head on the said table, and a 'slidable mandrel-frame carrying a revoluble mandrel adapted to engage the paper on the said recessed head, substantially as shown and described.

A machine for forming paper tubes, provided with a rolling and cutting table, a slidable mandrel-frame, a knife-frame pivoted in the said mandrel-frame and carrying knives for cutting a sheet of paper into strips, and a revoluble mandrel in the said frame, for winding the strips into tubes7 substantially as shown and described.

3. A machine for forming paper tubes,l provided with a rolling-table adapted to support strips of paper, a bar for raising the forward ends ofthe said strips of paper, and a head having a recess, and removably held on the said table, the said head passing under the raised ends of the said strips of paper, substantially as shown and described.

4. A machine for forming paper tubes, provided with a slidable frame carrying a revoluble mandrel, a knife-frame pivoted in the said slidable frame and spaced cutting disks or knives carried by the said knife-frame, for cutting the sheet of paper into strips, the mandrel serving for rolling the strips into tubes, substantially as shown and described.

5. A machine for forming paper tubes, provided with a roiling-table, a gage adapted to be swung upon the said table for placing the sheet of paper in proper position on the table, a recessed head removably held on the said table, and adapted to engage the strips of paper to be rolled into tubes, and a slidable mandrel-frame carrying a revoluble maudrel, for engaging the paper in the said recessed head and for winding the paper into tubes, substantially as shown and described.

G. A machine for forming paper tubes provided with a device for lifting one end of the paper, a recessed head adapted to pass under the uplifted end of the paper, and a mandrel for engaging the uplifted end of the paper to press it into the recessed head, substantially as shown and described.
